As part of migrating to common clk framework usage in DaVinci SoCs, clock.h and clock.c are being deprecated as the pll and psc clock drivers are moved to drivers/clk/davinci. The relevant PLL defines are moved to include/mach/pll.h and will be used by SoC specific code instead of using clock.h. The psc.c code is being deprecated as the psc specific code is moved to the drivers/clk/davinci. So the extern definitions are not used anymore and is now conditionally included.
